Routeing problem

[foned00d]

We change the IP address of our Solaris 9 box and now we can't get connected to one endpoint.

here is the error while tracerouting to xxx.xxx.222.11,
traceroute: Warning: Multiple interfaces found; using xxx.xxx.222.13 @ ce0
traceroute to xxx.xxx.222.11 (xxx.xxx.222.11), 30 hops max, 40 byte packets
1 xxx.xxx.222.2 (xxx.xxx.222.2) 2.887 ms !X * 1.614 ms !X


Any suggestions on where to look? Below is the hosts and netmasks files.

Just looking for suggestions on where to look as I can't see anything wrong here

netstat -rn

Why is it taking a route (.2) it is a direct connect.

Do you see .11 in the arp table?

 

[foned00d]

Not sure, All I did was replace the existing IP entries with the new ones... here is the netstat, as far as I know I shoul dbe talking out ce0 to the .11 address
# netstat -rn

Did you do this "on the fly"?

The reason I ask is that .17 seems to be your default router which isn't in your net range (I think), and .1 shouldn't be part of the equation. Unless you are running some route daemons...

 

[foned00d]

we have 2 interfaces, .17 is the gateway for .25 (eri0)
and .1 is the gateway for the .13 (ce0)

 

[foned00d]

The problem seems to be the server is trying to send packets destined for the local subnet to the subnet’s gateway. The gateway will drop those, we should never send traffic local to the subnet to the gateway on the subnet. But I can't figure why the server is doing this..

 

[elgrandeperro]

do a netstat -rnv to see the masks.
